Description

Technical Field

[0001] The present invention relates to the field of optical communication, in particular to a receiving antenna for an optical communication system. Background Art

[0002] Optical communication is a communication method that uses light waves as a transmission medium. Light waves and radio waves are both electromagnetic waves, but light waves have higher frequencies and shorter wavelengths than radio waves. Optical communication offers advantages such as wide bandwidth, high communication capacity, and strong resistance to electromagnetic interference. In optical communication systems, information is transmitted in the form of light signals, and computation and processing are performed in the form of electrical signals. The propagation of optical signals requires the conversion and transmission of optical signal transmitters and receivers.

[0003] Wireless transmission of optical signals is achieved through the use of antennas for transmission and reception. An antenna is a transducer that converts guided waves propagating along a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or vice versa. It is a component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communications, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy that utilize electromagnetic waves to transmit information rely on antennas. Antennas can be categorized as transmitting antennas or receiving antennas based on their nature of operation.

[0004] The primary function of a receiving antenna is to convert electromagnetic wave energy into high-frequency current energy. This current is induced within the radio wave field, generating an electromotive force at the antenna's output. This induced electromotive force then transmits current to the wireless receiver via the feeder, thereby completing the reception and conversion of electromagnetic wave signals.

[0005] Most existing receiving antennas are fixed, but the strength of different electromagnetic wave signals varies at different locations in the radio wave field. To ensure the integrity and clarity of signal reception, a mobile receiving antenna is needed. However, existing mobile antennas are usually small, have poor functionality, and low sensitivity. Larger antennas are usually integrated, which is not easy to disassemble, move, and maintain. They usually need to be fixed with screws during installation, but this condition is often not available in vehicle-mounted or outdoor mobile environments.

One end of the first rotating shaft 38 is coaxially connected to the second motor 39; the first gear 37 is driven to rotate by the second motor 39.

[0043] Specifically, the steering mechanism 3 also includes a mounting sleeve 310, two guide ridges 311 are symmetrically provided on the inner side wall of the mounting sleeve 310, and a threaded through groove 312 is provided in the middle of the bottom surface of the mounting sleeve 310; a semicircular steering gear 313 is fixedly installed on the outer side of the mounting sleeve 310, the steering gear 313 is clamped in the limiting arc groove 36, and the steering gear 313 is engaged with the first gear 37; two limiting sleeves 314 are symmetrically provided on the outer side wall of the mounting sleeve 310, and the upper ends of two fixed support frames 315 are inserted into the two limiting sleeves 314, and the lower ends of the fixed support frames 315 are fixed It is connected to the outer wall of the steering mounting block 34; the steering gear 313 is engaged with the first gear 37.

[0044] Specifically, the straight line where the two limiting sleeves 314 are located is perpendicular to the straight line where the steering gear 313 is located. The steering gear 313 rotates with the straight line where the two limiting sleeves 314 are located as the rotation axis.

[0045] Specifically, the connecting mechanism 4 includes a connecting sleeve 41 fixedly installed at the lower end of the base block 12, and two positioning guide grooves 42 are symmetrically arranged on the outer side of the connecting sleeve 41, and the positioning guide grooves 42 are adapted to the guide ridges 311; a sleeve groove 43 is coaxially arranged on the bottom surface of the connecting sleeve 41, and a fixed card groove 44 is coaxially arranged on the top of the sleeve groove 43; the positioning guide groove 42 is adapted to the guide ridges 311, and when installing, the two are clamped together to prevent the connecting sleeve 41 from rotating on the installation sleeve 310, thereby facilitating the synchronous rotation of the two.

[0046] Specifically, the connection mechanism 4 also includes a threaded rod 45 screwed in the threaded through groove 312, a handle 46 is provided at the lower end of the threaded rod 45, and a socket block 47 is sleeved on the upper end of the threaded rod 45, and the socket block 47 is located inside the mounting sleeve 310; a connecting plate 48 is provided at the upper end of the socket block 47, and a rotating connecting rod 49 is hinged on both sides of the connecting plate 48, and a cylindrical pressing block 410 is provided at the other end of the rotating connecting rod 49; a fulcrum shaft 411 is passed through the middle of the rotating connecting rod 49, and the fulcrum shaft 411 is fixedly installed in the mounting sleeve 310; the threaded rod 45 can be manually screwed by the handle 46, and the threaded rod 45 is limited by the socket block 47 to prevent the threaded rod 45 from slipping out of the mounting sleeve 310; the fulcrum shaft 411 provides a rotating fulcrum for the rotating connecting rod 49. During the rotation of the threaded rod 45, due to its threaded connection with the threaded through groove 312, the threaded rod 45 will move up and down, thereby driving the sleeve block 47 sleeved on the threaded rod 45 to move up and down, and then driving the rotating connecting rod 49 to rotate, thereby pressing the two columnar pressing blocks 410 downward; when the connecting sleeve 41 is engaged with the mounting sleeve 310, the two columnar pressing blocks 410 will be sleeved into the sleeve groove 43, and when the threaded rod 45 rises, the two columnar pressing blocks 410 move away from each other and press downward, and will extend into the fixed card groove 44 and conflict with the inner side wall of the fixed card groove 44, thereby fixing the connecting sleeve 41 in the mounting sleeve 310; similarly, when it needs to be disassembled, the threaded rod 45 is rotated in the opposite direction and lowered, so that the column pressing blocks 410 are reset, and the connecting sleeve 41 can be removed from the mounting sleeve 310.

When the permanent magnet 56 is rotated to contact the brass 53, the cast iron base 51 will generate a strong magnetic force, thereby attracting the cast iron base plate 31, thereby facilitating the installation and fixation of the radar 11. When the radar 11 needs to be transferred or removed, the permanent magnet 56 is rotated to separate from the brass 53, the cast iron base 51 will lose its magnetic force, and the cast iron base 51 and the cast iron base plate 31 will be separated.

[0048] When the present invention is in use, the limit bolt rod 16 is pulled out of the hollow sleeve 13, and the limit protrusions 19 on both sides of the lower end of the limit sleeve 18 are clamped in the limit guide groove 14, thereby limiting the limit sleeve 18. During this process, the limit sleeve 18 can only slide up and down in the hollow sleeve 13, but cannot rotate; and when the limit protrusion 19 slides from the limit guide groove 14 to the anti-slip groove 15, at this time, the limit sleeve 18 is manually rotated, but due to the blocking of the limit bolt rod 16, the limit sleeve 18 can only rotate in one direction. After rotating a certain angle, the limit protrusion 19 is clamped in the anti-slip groove 15, and under the action of the top pressure spring 171, the fixed pressure ring 17 will conflict with the limit protrusion 19, thereby achieving a fixing effect and preventing the limit sleeve 18 from rotating by itself.

[0049] The positioning guide groove 42 of the connecting sleeve 41 is engaged with the guide protrusion 311 of the mounting sleeve 310, and the connecting sleeve 41 is sleeved into the mounting sleeve 310. The two cylindrical pressure blocks 410 will be sleeved into the sleeve groove 43. The threaded screw rod 45 is turned by the handle 46 to drive the threaded screw rod 45 to rise. The two cylindrical pressure blocks 410 move away from each other and press downward, extending into the fixed slot 44 and contacting the inner wall of the fixed slot 44, thereby fixing the connecting sleeve 41 in the mounting sleeve 310.

[0050] Place the cast iron base plate 31 flat on the roof or fixed plate, and place the cast iron base 51 under the roof or fixed plate, with the cast iron base 51 corresponding to the position of the cast iron base plate 31. Turn the rotating handle 55 to rotate the permanent magnet 56 until it contacts the brass 53, so that the cast iron base 51 generates magnetic force, and the cast iron base plate 31 is adsorbed on the roof or fixed plate.

[0051] After the installation is completed, start the radar 11 and connect it to the control end; start the first motor 33 to drive the steering mounting block 34 to rotate 360 ​​degrees on the horizontal plane; start the second motor 39 to drive the first gear 37 to rotate, and drive the steering gear 313 to rotate synchronously, so that the radar 11 can be rotated on the vertical plane. In conjunction with the rotation of the steering mounting block 34 on the horizontal plane, the radar 11 can be rotated in three dimensions, thereby facilitating signal collection.

[0052] When the signal receiving work is completed, the permanent magnet 56 is rotated to separate from the brass 53, and the cast iron base 51 will lose its magnetic force. The cast iron base 51 and the cast iron bottom plate 31 can be removed, and then the threaded screw rod 45 is rotated in the opposite direction and lowered to reset the cylindrical pressure block 410, and the connecting sleeve 41 can be removed from the mounting sleeve 310; then the limiting sleeve 18 is rotated, and when the limiting protrusion 19 conflicts with the limiting bolt rod 16, the limiting protrusion 19 is pushed into the limiting guide groove 14, and then the extension rod 111 is pushed to retract the extension rod 111 into the hollow sleeve 13; in this way, the entire system is disassembled for easy storage and transfer.
